PHP - Echo Once Inside A While Loop.

This probably doesn't matter much, but I am using a 'Display' class for final output to the browser.

The class will display the obvious HTML header and then display either the full site or the mobile site.

It also displays the CSS / JS (which is previously selected in the page-specific controller code as there are variations based on server-side checks).

Basically it is the ONLY class that actually needs to send anything to the browser.

When I begin output and echo inside the class, that is the end of the script - there is no more server-side code to execute.

If I shouldn;t echo inside the class, is it that bad to do so?

Hello guys im new to php i been coding for like a week now, i  need some help here i have been stuck for like 6 hours XD,is it possible to write an IF Statement inside an echo?


//this is what i want to do 
// echo a table and a delete button
// and if you click on the delete button it echoes out "DELETED"


echo "

<table width='528px'>
<tr>
<td>
</td>
<td>
<center><font size='5'>$tittle</font></center><br>
</td>
</tr>
<tr>
<td>
</td>
<td>
$message
</td>
</tr>
<tr>
<td>
</td>
<td>
<font size='1'>Posted By:<font color='green'>$author</font> on <font color='gray'>$date</font> at <font color='gray'>$time</font></font>
<input id='delete' name='delete' type='submit' value='Delete' >

 if ($_POST['delete']) {  echo "DELETED";     } 


<td>
</td>
</tr><br><br>
</table>

";

Im having a problem with getting the quotes correct with this. I can either get the variable to work in the href and img src or in the css. Anyone have any ideas on this. Cuase im really stuck.

This allows the $address and $cos to echo in but not the css variables


<td><?php echo "<a href='planet_profile.php?planet=$address'>
<img src='images/star.jpg' id='$cos' 
style='position:absolute;' left:'$b_x px;' top:'$b_y px;'></a>"; ?></td>


and this allows only the css variables to work


 
<td><?php echo '<a href="planet_profile.php?planet="' . $address . '">
<img src="images/star.jpg" id="' . $cos . '" 
style="position:absolute; left:' . $b_x . 'px; top:' . $b_y . 'px;"></a>'; ?></td>

Good Evening -  I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP. It works on a different part of the site within the admin panel but not here. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out...

// CATEGORIES

$query  = "SELECT * FROM cat";
$result = mysql_query($query);



while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

$catid = $row['id'];
$catname = $row['name'];

$output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\">
<a href=\"product.php?cat=$catid\">
<span>$catname</span>
</a>\n";


$querynav = "SELECT * FROM subcat WHERE pid = '$catid'";
$resultnav = mysql_query($querynav);

while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC))
{

$subcatid = $row['id'];
$subcatname = $row['name'];

$output .= "<ul class=\"level0\">
<li class=\"level1 nav-2-1 first\">
<a href=\"product.php?cat=$catid&subid=$subcatid\">
<span>$subcatname</span>
</a>
</li>
</ul>
</li>";
}

}

hello,  im trying to add a hyperlink that launches in a new window to the following (in the last column)  any ideas?

Hi

I am trying to use the nl2br function like this

while ($row = mysqli_fetch_array($query)) {
//May need this later to output pictures   
//     $imageURL = 'upload/'.rawurlencode($row["filename"]);
  echo
  
   "  <div class='divTableRow'>
<div class='divTableCell'>{$row['User']} ;</div>
<div class='divTableCell'>nl2br({$row['CommentText']});</div>
</div>


    \n";
}

However the output just looks like the attached picture.

When I check in the sql db I can see the line breaks when doing a select * from Table ;

 

I'm redoing my login script using functions and a basic switch function checking against a $_GET variable (hope you guys know what I'm talking about).

What I want to do is create two functions:

1 that displays the login form
and 1 that processes the information

The form tag would look like this:
<form action=\"<?php $_SERVER['PHP_SELF']?>?action=process\" method=\"post\">
</form>

Here's my switch statement:
Code: [Select]
<?php

//****************************************
//****************Action******************
//****************************************

switch ($_GET["action"]) {
default:
case "index":
if (!$_SESSION["member"]) {
if (!$timeout) {
display_form();
} else {
echo $timeout_error;
}
} else {
echo "You are already logged in.";
}
break;
case "process":
if (!$_SESSION["member"]) {
if (!$timeout) {
process_form();
} else {
echo $timeout_error;
}
} else {
echo "You are already logged in.";
}
break;
}

?>

This runs as soon as "login.php" loads.

It'll automatically run the commands under case "default" and "index". It'll first check to see if the member's logged in. If not, it'll then check to see if "$timeout" is true ($timeout becomes true if the member has attempted to login 5 times and failed). If not, it'll display the login form, by running "display_form()".

Once the form has been filled and submitted, the commands under case "process" will be performed. Again it will first check to see if the member's logged in. If not, it'll check to see if "$timeout" is true. If not, it'll start validating the forms.

For the validation, I've created a variable called "$errors_found", and scripted one if statement checking to see if the email and password exist. If so, the variables "$rm_field_un" and "$rm_field_pw" become true, as well as "$errors_found".

So, back to submission of the form...

If "$errors_found" is true, display the form (when the form is displayed, there will be an if statement within that says "<?php if ($rm_field_un) { echo "Username is wrong."; } ?>", which will be displayed right underneath the username field and label. Same with the password elements). If "$errors_found" is not true, go ahead and register the member.

Now, here's where I need help, because I'm really confused as to how to accomplish this.

The "display_form()" function will contain a single variable called "$login_form". It will contain a value of the HTML constructed login form, and the function will return the variable.

Remember how I stated in the third paragraph up that I will have <php> statements within the form which would display errors if necessary? Well, how do I put those if statements within the HTML, which is contained within the variable?

If that last question confuses you, allow me to present you with an instance:
Code: [Select]
<?php

function display_form() {
$login_form = "
<form name=\"login_form\" method=\"post\" action=\"<?php $_SERVER['PHP_SELF']?>?action=process\">
Username:
<input type=\"text\">
<?php if ($rm_field_un) { echo "Username is wrong"; } ?>
";

return $login_form;
}

?>

See what I mean?

This code confuses me ALOT. I'm not sure if the <php> tags are needed as it is already contained within existing ones, or what. Can somebody please help me out?

Any and all help is much appreciated. =D

Trying to figure out how to make it so name is a link to the profile when its echo
anyone know how to do this?

im at a huge stand still


Code: [Select]
<?php 

                                                $sql = "SELECT name FROM users WHERE DATE_SUB(NOW(),INTERVAL 5 MINUTE) <= lastactive ORDER BY id ASC"; 
$query = mysql_query($sql) or die(mysql_error());
$count = mysql_num_rows($query);
$i = 1;
while($row = mysql_fetch_object($query)) {
 $online_name = htmlspecialchars($row->name);


   echo '<a href="Inbox.php">"'[$goauld]'</a>"'; ?>

Hi I am new to PHP and this is my first post one here so appologies is this questions seems a bit dumb!

I have an if clause such that if a button is pressed on my web page then i want to reload the page and include a new form on it.

I am having a problem getting the $_SERVER['PHP_SELF'] command to work from iside a echo command. I must not be escaping the code correctly with back slashes:

I currently have the line :

 
echo"<form method=\"POST\" action=\"\<?$_SERVER['PHP_SELF']?\>\">";


However this doesnt seem to work as my page just doesnt display in the browser.

Any advice is much appreciated.

Thanks for taking the time to read.

how do i get the image to show as the code i have is echoing what i have been told is binary, not confirmed.  and not the images.

all images are .jpg

Code: [Select]
$allowed_types = array('png','jpg','jpeg','gif');
$imgdir = '/home/mysite/ftpfolder';
$imgFilesArray = scandir($imgdir);
foreach ($imgFilesArray as $imgkey => $imgvalue)
{
$imgInfo =  pathinfo($imgdir . '/' . $imgvalue);
$imgExtension = $imgInfo['extension'];
if(in_array($imgExtension, $allowed_types))
{
readfile($imgdir . '/' . $imgvalue);
//echo '<img src = "'. $imgdir  .'/'. $imgInfo['basename'].'" alt="" />';
}
}

images are FTP'd to the ftpfolder and can not be placed anywhere else but this folder due to security reasons.

Hi! My question is probably simple but I've been scratching my head for hours now... I'm pretty new to php. I have an online form for orders; when submitted, an email is sent to the shop manager containing the info the client has filled in. So I pass all the info in the code below, but I can't manage to echo the array containing the order's items/qty/item_code. (I'm using Wordpress, Oxygen Builder, Metabox and Code Snippets, if that helps). Here's the code (used as a Code Snippet):

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    if ( 'command-form' !== $config['id'] ) {
        return;
    }

    $name = rwmb_meta( 'name', '', $post_id );
    $email = rwmb_meta( 'email', '', $post_id );
    $phone = rwmb_meta( 'phone', '', $post_id );
    $orders = rwmb_meta( 'order', '', $post_id ); */ ---> this is the array I wish to show the elements from (array --> [0]:{item:"item", qty:"qty", code:"code"]}, [1]:{}, etc...} */
    $comments = rwmb_meta( 'comments', '', $post_id );
    $reception = rwmb_meta( 'reception', '', $post_id );
    $destination = rwmb_meta( 'destination', '', $post_id );
    $payment = rwmb_meta( 'payment', '', $post_id );

    $body = "Vous avez reçu une nouvelle commande en ligne!

Nom: $name
Courriel: $email
Téléphone: $phone
Commande: */ ---> this is where I want it displayed, but since it is within $body = " ", I can't seem to be able to use foreach( ) or even print_r( )... */
Commentaires: $comments
Réception: $reception
Paiement: $payment";
     

    $headers = ['Content-type: text/html', "Reply-To: $email"];
    wp_mail( 'address@domain.com', 'Nouvelle commande en ligne', $body );
}, 10, 2 );

 

Help with this would be greatly appreciated! Please let me know if any details are missing. Thanks in advance!

my output is this below:

Course: INFO101 - Bsc Information Communication Technology Course Mark:



Course: INFO101 - Bsc Information Communication Technology Course Mark:


Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B

Session: AAB Session Mark: 72 Session Weight Contribution 20%

Session: AAE Session Mark: 67 Session Weight Contribution 40%

Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B

Session: AAD Session Mark: 61 Session Weight Contribution 50%

As it shows 2 different Modules, it shows the "Course" details twice, I only want the "Course" details appear once as you can see both course details are the same.

How can I display the "Course" Details only once in the foreach loop.

To display the "Course" details I use this code: echo Code: [Select]
`"<p><br><strong>Course:</strong> {$courseId} - {$courseName} <strong>Course Mark:</strong></p><br>\n";`

Below is the code for the function and foreach loop:


Code: [Select]
     function outputModule($courseId, $courseName, $moduleId, $moduleName, $sessionData)
        {
       
            if(!count($sessionData))
            {
                return false;
            }
       
            $markTotal = 0;
            $markGrade = 0;
            $weightSession = 0;
            $courseTotal = 0;
            $grade = "";
            $sessionsHTML = "";
           
            foreach($sessionData as $session)
            {
       
                $sessionsHTML .= "<p><strong>Session:</strong> {$session['SessionId']} <strong>Session Mark:</strong> {$session['Mark']}</strong> <strong>Session Weight Contribution</strong> {$session['SessionWeight']}%</p>\n";
               
                $markTotal += round($session['Mark'] / 100 * $session['SessionWeight']);
                $weightSession  += ($session['SessionWeight']);
                $markGrade = round($markTotal /  $weightSession * 100);
                     
                if ($markGrade >= 70)
                {
                    $grade = "A";
                }
       
                else if ($markGrade >= 60 && $markGrade <= 69)
                {
                    $grade = "B";
                }
       
                else if ($markGrade >= 50 && $markGrade <= 59)
                {
                    $grade = "C";
                }
       
                else if ($markGrade >= 40 && $markGrade <= 49)
                {
                    $grade = "D";
                }
       
                else if ($markGrade >= 30 && $markGrade <= 39)
                {
                    $grade = "E";
                }
       
                else if ($markGrade >= 0 && $markGrade <= 29)
                {
                    $grade = "F";
                }
        }
       
            echo "<p><br><strong>Course:</strong> {$courseId} - {$courseName} <strong>Course Mark:</strong></p><br>\n";
            $moduleHTML = "<p><strong>Module:</strong> {$moduleId} - {$moduleName} <strong>Module Mark:</strong> {$markTotal} <strong>Mark Percentage:</strong> {$markGrade} <strong>Grade:</strong> {$grade} </p>\n";
       
            return $moduleHTML . $sessionsHTML;
        }

Hi,

Have a text file that is being read. I want to print the contents however I want each line of the text file to appear on a new line in the browser.

So far
$str = file_get_contents('records.txt');
$lines = explode("\n", $str);
echo $lines[0];

Help appreciated

I wrote a short script that takes a list of keywords and does a Google search to find how often they are used in the title of a page.  However, I cannot get it to echo the results in real time.  On one server I use it works fine.  On the other it runs the entire list and then outputs everything in the end.  The problem is sometimes this takes several minutes and therefore it times out after not receiving a response.

Any suggestions?

Thanks in advance.

<?php 

$file = file('words.txt'); 

$results = ''; 
foreach ($file as $line) { 
    $data     = file_get_contents("http://www.google.com/search?hl=en&q=allintitle%3A%22" . urlencode($line) . "%22&btnG=Google+Search"); 
    preg_match('/of about <b>([0-9,]*)?<\/b>/si', $data, $number); 
    $results .= $line . ";" . $number[1]; 
    echo $results . "</br>"; 
    $results = "";
    sleep(2);
} 

?>
